芳纶纳米纤维（ANFs）由于其一维纳米尺寸、高长径比、高比表面积、优异的强度和模量以及令人印象深刻的化学和热稳定性而在各种应用中受到极大关注。自2011年以来，它被认为是一种性能优异、最具发展前景的纳米材料，受到越来越多的关注。然而，目前尚无文献综述ANF的研究进展和面临的挑战。本文综述了ANF的制备方法及其优缺点，并对去质子化法制备ANF所面临的挑战和研究进展进行了综述。介绍了不同宏观形貌的ANF基先进材料的制备方法和研究进展，包括一维ANF气凝胶纤维、二维ANF薄膜/纳米纸/涂层、三维ANF凝胶和颗粒。此外，还介绍了ANF在纳米复合材料增强体、电池隔膜、电绝缘纳米纸、柔性电子器件、吸附过滤介质等方面的应用。此外，ANF的未来发展可能面临的挑战和展望。本文综述了ANF和ANF基材料的研究进展，指出ANF及其基材料将促进下一代先进功能材料的发展。
Aramid nanofibers (ANFs) are of great interest in various applications due to its 1D nanoscale, high aspect ratio, high specific surface area, excellent strength, and modulus as well as impressive chemical and thermal stabilities. It is considered as one of the most promising nano-sized building blocks with excellent properties and has therefore drawn increasing attention since 2011. However, no review has summarized the research progress and the prospective challenges of ANF. Herein, the methods of ANF fabrication and their relative merits are comprehensively discussed together with the challenges and progress in the deprotonation method for preparing ANF. The fabrication methods and development of ANF-based advanced materials with different macroscopic morphologies, including the 1D ANF aerogel fiber, 2D ANF film/nanopaper/coating, and 3D ANF gel and particle are also described. Furthermore, the applications of ANF in nanocomposite reinforcement, battery separators, electrical insulation nanopaper, flexible electronics, and adsorption and filtration media are presented. Additionally, the possible challenges and outlooks toward the future development of ANF are highlighted. This review indicates that the ANF and ANF-based materials mentioned herein will boost the development of next-generation advanced functional materials.
